Everything you should know about Elektra, the femme fatale of 'Daredevil' season 2

Netflix just released its second full trailer for "Daredevil," showing off Matt Murdock's deadly former flame, Elektra Natchios. Elodie Yung will star as Elektra, the mysterious assassin with a lot to hide.

Who is Elektra and why should you care? She's deeply tied to Matt's past, his mentor, and the upcoming battle to save Hell's Kitchen.

Don't know much about the Grecian femme fatale? Here's what you should know about Elektra before her Daredevil season two drops on March 18.

Elektra first appeared in 1981's "Daredevil #168" as "Elecktra." She began as a one-off character, but went on to have an expanded, complicated love story with Matt.

In the comics, Elektra Natchios is a Greek law student who Matt first meets at Columbia University in New York. She's the daughter of a Greek ambassador, but both she and her father are kidnapped and held for ransom. Matt tries and fails to rescue his then-girlfriend and her father is killed as a result. Elektra, feeling helpless, left school to begin training in martial arts, vowing to never be that weak again.

They may be heading down a similar path in the show. In season one, Foggy asked Matt about a "Greek girl" he used to date.

Last season, during a flashback, Foggy references Elektra while he and Matt are still Columbia students. This seems like a nod to Elektra and Matt's original story, though we aren't sure yet how much will stay the same.

In the comics, Elektra was also trained by Matt's mentor.

Interestingly, when Elektra began training her mentor was also Stick, Matt's blind mentor who appeared in the first season. In season one, Stick shows up unannounced (frustrating Matt, who felt like Stick abandoned him) and tells Matt of a war involving both Fisk's thugs and the Japanese mafia. In the new trailer, he returns and warns Matt that "The Hand" are even more powerful than he realizes.

Stick's reappearance in Elektra's "Daredevil" trailer also implies that her training with him will also remain the same. Although she's debuting for the first time in season two, it's clear she has many ties to the first season and Matt's past.

Elektra may not be the most trustworthy woman.

In the trailer, when Elektra and Matt meet again in the present day, she warns him his efforts to rid Hell's Kitchen of crime only strengthened The Hand's efforts. Matt simply neutralized their enemies (The Russians, Fisk, etc) while they bided their time.

This is where it gets complicated.

In the comics, Elektra originally gained her martial arts skills from Stick, Matthew's blind mentor. But, desiring to grow even more powerful, she joined The Hand and learned how to kill. Remember that Matt rarely kills his enemies. Elektra will likely be less merciful. Stick has a brief cameo in the new trailer, warning against The Hand and their new power in Hell's Kitchen. Who's side will Elektra take?

While the trailer focuses on Elektra and Matt teaming up, the actress has made it clear that Elektra has her own agenda.

Marvel

In an interview about the character, actress Elodie Yung called Elektra a "sociopath" with her own agenda.

"This world is a game for her," she told Collider. "It’s like a chess game, and what motivates her is what she wants. She’ll use anything she needs to use to get to her goal, and if she needs to kill people, she will. She has this coldness in her, and I tried to keep that."

What are her goals? What exactly does she want from Matt? Yung promises more nuance and an exploration of Elektra's motivations.

"But on the other hand, we wanted to create a character with different layers," she said. "I think Elektra isn’t a bad person, but she’s not a good person. She’s a person with different traits, with layers, and she’s seeking who she is."

The new trailer may be subtly implying something about Elektra's true allegiance. Notice how the trailer immediately shows a shot of Elektra's hand.

Then again, when seated at the bar, we see another close shot of her hand.

And then finally, when we see Elektra with another person — could she have reunited with Matt? — there's another shot of her hand. What does it mean?

Is Elektra still an agent of The Hand? In the comics, she wavers between Stick's benevolent order of martial artists and the deadly assassins in The Hand. Perhaps this will be part of the discovery of who she "really is."
